The results of linear discriminant analysis with a discrimination rate of 96% indicated whole blood Ca, Co, Cu, Fe, K, Mg, Na and Zn, serum Ca, Cu, Na and Ni, and urine Cd, Co, Fe and Mn being the strongest predictors of illness. TGCT patients had a significant increase in serum and blood Cu and decrease in serum Fe and blood Zn with cancer progression. Significantly higher concentrations of Al, As, Pb, and Ni in whole blood/serum of men with TGCT confirm the hypothesis that low-level environmental exposure to these elements may contribute to cancer development. Relationship between elements concentrations and treatment outcomes should be carefully monitored during cancer treatment since high concentrations of commonly used platinum-based chemotherapeutics may additionally disturb the homeostasis of elements.</p>","PeriodicalId":53200,"journal":{"name":"Journal of Environmental Science and Health Part C-Toxicology and Carcinogenesis","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/26896583.2021.1874234","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25361480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
